This article reviews modern scientific literature devoted to the study of the biological activity of flagellin to develop on its basis new effective medicines. One of the most promising areas of research is the use of recombinant flagellin as adjuvant in vaccines against the causative agents of different infectious diseases first of all against influenza. The characteristics of the recent flagellin containing vaccines and data on immunogenicity studies of new hybrid molecules are presented. Several influenza vaccines developed by VaxInnate Corporation (USA) undergo different phases of clinical trials. The effectiveness of Russian influenza vaccines (Russian Institute of influenza) is currently being studied in animals. The second most important direction is based on the study and use of radioprotective properties flagellin. Currently in the world there is one flagellin based drug entolimod (Cleveland BioLabs, USA), which radioprotective efficiency was studied in experiments on mice and primates. The overview analyzed the study of the mechanisms of the radioprotective action of flagellin based drugs as a TLR5 agonists presented by different authors. Also results of researches proving the potential of flagellin and its derivatives as radiation countermeasure agents are reviewed.
